Flow Cytometric Analysis Using Lipophilic Dye PKH-2 for Adhesion of Vibrio cholerae to Intestine 407 Cells

Abstract

A comparative study of indirect and direct flow cytometric analysis for adherence of Vibrio cholerae to Intestine 407 cells was performed. The direct flow cytometric analysis employed the lipophilic dye PKH-2. It was concluded that direct flow cytometry using the lipophilic dye PKH-2 is useful and convenient for analyzing bacterium-host cell interactions, since it does not require any specific antibody as the first antibody.
